    When two orbitals can interact and they are of the same initial energy, then the two resultant combination orbitals are derived equally from the two initial orbitals. (Second order perturbation theory). [6] In addition, while the valence bond theory predicts H 2 O is sp 3 hybridized, the prediction from MO theory is more complex.

  6. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    Water is the chemical substance with chemical formula H 2 O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. [26] Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue color. [4]

    The upper tier encloses an aqueduct that carried water to Nimes in Roman times; its lower tier was expanded in the 1740s to carry a wide road across the river. Water is an inorganic compound with the chemical formula H 2 O. It is a transparent, tasteless, odorless, and nearly colorless chemical substance.
